    Headlamp beams

    Looks like you've built an excellent, adaptable to differing conditions, all around useful headlamp there, Bolster. In a way though, doesn't it seem kind of pitiful that you have to resort to a home built headlamp to get a beam that is useful for your work environment? Other than one Petzl...

    Headlamp beams

    Great idea there, Bolster. I'm sure Zlight could do that without too much trouble, and I'm betting it'd be one of the best headlamps out there. The trouble I have with most modern headlamps, is that when I started using headlamps for caving and outdoor activities, they were carbide headlamps...

    Headlamp beams

    Sorry for not being clearer. I didn't mean the design approach itself was undesirable for a backpacking headlamp, but was thinking in terms of rapid battery consumption by a typical AAA format headlamp when running both spot and flood emitters. But, I now remember that the Storm can't do that...

    Headlamp beams

    gcbryan, didn't you mention somewhere that you rather liked the flood beam capability provided by the Storm? Storm has two separate flood emitters, IIRC. Did you tape over the flood emitters, the throw emitter, or all of them? The basic design concept of having one throw emitter and also a...

    Post if you've never owned a SF Saint!

    Too expensive for its capability. Plus, isn't the Saint designed to run on CR123 cells, with AA cells only as a secondary, sub-optimal power source? Or is that Saint Minimus? Anyhow I've disposed of all of my CR123 powered lights, and don't forsee ever buying any CR123 format light in the...

    One man's search for the ideal bushwalking headlamp and other lights

    That's OK, bears make me nervous too. :> Most black bears, most of the time, are completely harmless. However, a very few black bears have been known to track, then stalk, then kill, then eat humans - although thankfully that's very rare. Every once in a while I'll notice an article about a...

    One man's search for the ideal bushwalking headlamp and other lights

    Excellent job of debunking a myth, bbb74. Not having visited Australia I don't have any first hand knowledge of its hazards. From casual reading and watching various nature shows, I had long had the idea that the great outdoors was safer in Australia than in North America, mainly because of...

    One man's search for the ideal bushwalking headlamp and other lights

    So you consumed an average of 2.5 lithium AA cells per day - makes me curious as to what you are doing to consume cells at that rate. Backpacking at night, major night hikes, or maybe a little bit of caving on the side? ;> I know two guys who thru-hiked most of the Appalachian Trail carrying...

    Post if you've never owned a Zebralight!

    I've never owned one. They do look to be superb lights in nearly every way except reliability. Their very slow turn around time for service is also a negative for me. Odds seem to be good that I'd get a decent one, but the whole crap shoot nature of the experience just puts me off from buying...

    New HL from Petzl: Pixa series

    +1 A few times over the years my primary light source (helmet mounted carbide) suffered catastrophic failure - meaning it was unfixable in the cave. At those times, I'd have been absolutely thrilled to have been able to pull a long runtime Petzl Pixa out of my caving pack and strap it to my...

    New HL from Petzl: Pixa series

    One model used in optics treats light as an Electro-Magnetic Wave, which works very well for many purposes. Another model treats light as discrete particles - photons - which takes into account the quantum mechanical nature of light. This also works very well for many purposes. Neither model...

    New HL from Petzl: Pixa series

    The standard way is to measure the angle off the center axis where the beam intensity down is down to 70 percent of the central peak beam intensity. The reason for using 70 percent intensity, is because 70 percent squared is very close to one-half. The reason for squaring is because beam...

    Storm electronics question

    Since nobody else has replied, I'll take a stab at it. Not having a Storm to look at this is rather speculative. Depends on whether it has separate drivers for the spot and flood emitters. If there are two separate driver circuits, then what you are proposing should be a fairly straight...

    Princeton Tec EOS - 7 years on the market.

    Thanks robo. I remembered the low being too bright for my tastes. Had hoped that PT had changed to a lower low for this version, but alas that's still too bright a low for me. .

    ITP H01 AAA Headlamp

    Wowsers, that was fast. Did you get it from a local store? Glad to read that your first impressions are good. Look forward to reading what you think after you've used it outdoors a bit. Yeah, some people seem to invest a WHOLE LOT of emotion about picking one type cell over another. And...

    ITP H01 AAA Headlamp

    Yeah, I came very close to ordering one. But the regulars on this forum were very down on it so I didn't. Really, for 30 bucks, there are a number of better headlamp deals out there. Frankly I'm more interested in its potential to do double duty as an EDC light rather than using it as a...

    Princeton Tec EOS - 7 years on the market.

    Does anyone know what EOS outputs on medium and low? Or if you have a 70 lumen EOS, can you guesstimate its low output? From the figures here it looks like low might be about 6 lumens? I've never owned an EOS, but was able to try out an earlier version. Using it inside a tent for close up...

    ITP H01 AAA Headlamp

    Great, and after you try it out outdoors please post your thoughts here. Looks to be flexible enough in operation that I can't imagine not getting some use out of it. When not in use as a headlamp, this little guy could be a decent EDC light because you can leave the headband at home and carry...
